Description

Technology Field

[0001] The present invention relates to a symmetrical installation device that connects an unmanned aerial vehicle (drone, 90) and an attachment (35) and assists in maintaining balance by distributing the weight of the attachment (35). The device comprises a control bar (20) and a support angle (30) that are movably coupled to both sides of a main body (10), a reciprocating plate (40) that moves together with the control bar (20), and a capture part (45) that mutually connects the lower part of the skid bar (91) of the drone (90) and the reciprocating plate (40). Background Technology

[0003] As the flight performance and control technology of drones—unmanned aerial vehicles—advance, they are being utilized in various industrial fields, and are particularly actively used in the construction industry for safety inspections of various structures, aerial surveying, and field investigations.

[0004] As drones are utilized for a wide variety of purposes, the accessories mounted or attached to the drone airframe, such as imaging devices, sensing devices, positioning devices, and communication devices, are also becoming more diverse; consequently, there are many cases where the drone is operated by selectively attaching or detaching the aforementioned various accessories to the flight body.

[0005] Methods for connecting such attachments or cargo to the drone body include installing a frame or cargo box on the lower part of the drone body, and related prior art includes Patent No. 2006171. The problem to be solved

[0007] Conventional drone mounting devices, including Patent No. 2006171, are limited in their function to preventing the fall of mountings or cargo and supporting the aircraft during landing, and can be described as essentially being a simple box-like structure fixed to the lower part of the drone body.

[0008] Therefore, the function of attaching and detaching various attachments to accommodate the multi-purpose operation of the drone as described above could not be supported at all, and even if attachments were simply attached, the weight would inevitably be uneven, which would inevitably seriously threaten the flight stability of the drone.

[0009] In particular, it was fundamentally impossible to adjust the mounting position of attachments as the drone's specifications changed, which inevitably resulted in limiting the drone's functional expandability.

[0010] Furthermore, in conventional technology, mounting an attachment onto the drone airframe required complex fastening means and operations, which caused significant inconvenience and time consumption during the process of changing the drone's functions, inevitably lowering the operational efficiency of the drone. means of solving the problem

[0012] The present invention is devised to take into account the aforementioned problems, so that even complex mounting devices (35) mounted on a drone (90) can be mounted simply, quickly, and stably, and at the same time, not only is the balance of the drone (90) body not compromised at all despite the mounting of the mounting devices (35), but the mounting devices (35) can also be attached and detached quickly and easily without the use of complex fastening means or tools. In a drone mounting device, a control bar (20) is coupled to both sides of a main body (10) and has a support angle (30) attached to its outer side, a reciprocating plate (40) connected to the control bar (20) and moving together, and a capture part (45) that connects the skid bar (91) of the drone (90) and the reciprocating plate (40) are configured, wherein a pinion (15) is mounted in the center inside the main body (10), and a rack (25) is formed at the other end of the support angle (30) of the control bar (20), and the rack (25) and The symmetrical mounting device for a drone is characterized by the fact that pinions (15) are engaged with each other, a plurality of guide grooves (13) are formed by cutting into the upper plate of the main body (10), a protrusion (23) is formed on the upper surface of the adjustment bar (20), a reciprocating plate (40) is attached to the upper part of the protrusion (23) that passes through the guide groove (13), and when one side adjustment bar (20) is pressed in or pulled out, the pinion (15) engaged with the rack (25) rotates, and the other side adjustment bar (20) is also pressed in or pulled out.

[0013] In addition, the present invention is a symmetrical mounting device for a drone, characterized in that a plurality of coupling grooves (62) are formed on the bottom surface of the main body (10) and arranged radially with the center point of the main body (10) as an axis, a steel plate (63) is attached inside the coupling groove (62), and a self-attaching weight (60) is attached to the steel plate (63).

[0014] In addition, the present invention is a symmetrical mounting device for a drone, characterized in that a spherical protrusion (70) with a spherical surface formed on the lower side is formed at the center of the bottom surface of the main body (10). Effects of the invention

[0016] Through the present invention, when mounting various attachments (35) on a drone (90), simple, rapid, and stable mounting is possible, and setting work can be easily performed to stably maintain the balance of the drone (90) body despite mounting a large number of attachments (35).

FIG. 2 is a perspective view of the present invention FIG. 3 is an explanatory diagram of the control method of the present invention. FIG. 4 is an exploded perspective view of the present invention.

Specific details for implementing the invention

[0020] The detailed configuration and operating principle of the present invention are explained below with reference to the attached drawings.

[0021] First, FIG. 1 is a drawing illustrating the use of the present invention. As shown, the present invention is mounted on a lower skid bar (91) of a drone (90), and mountings (35) are mounted on each side of the device to maintain balance during flight of the drone (90).

[0022] That is, the present invention is a symmetrical mounting device that assists in maintaining the balance of a mounting device (35) mounted on a drone (90), and as shown in FIGS. 1 and 2, it is composed of a rectangular box-shaped main body (10), a control bar (20) which is coupled to both sides of the main body (10) so as to be axially movable and has a support angle (30) attached to its outer end, a reciprocating plate (40) which is connected to the control bar (20) and moves together with the control bar (20) when the control bar (20) moves axially, and a capture part (45) which mutually connects the lower part of the skid bar (91) of the drone (90) and the reciprocating plate (40).

[0023] In the present invention, the mounting device (35) mounted thereon may include a photographic device, a surveying device, a communication device, or a battery, and the mounting device (35) is attached so as to be detachably attached to the support angles (30) on both sides of the present invention as shown in FIGS. 1 and 2.

[0024] The mounting device (35), such as the aforementioned shooting equipment or battery, may be directly attached to both sides of the mounting device symmetrical installation device of the present invention, but may also be mounted in a form housed in a separate housing as exemplified in FIGS. 1 and 2, and the connection between the mounting device (35) and the support angle (30) may be made through a connecting member such as a bracket (36) as in FIGS. 2.

[0025] As shown in FIGS. 1 to 3, in the present invention, the support angle (30) on which the mounting (35) is mounted is joined to the outer ends of a pair of parallel adjustment bars (20), and a pair of adjustment bars (20)-support angle (30) assembly members are each joined to both sides of the main body (10), and the pair of adjustment bars (20)-support angle (30) assembly members are symmetrical with respect to the center point of the main body (10) in a planar plane.

[0026] That is, in the present invention, a plurality of adjustment bars (20) are configured parallel to the longitudinal central axis of the main body (10) in a planar shape. The outer ends of a pair of mutually parallel adjustment bars (20) are connected to a support angle (30) that is orthogonal to the adjustment bar (20) in a planar shape to form an adjustment bar (20)-support angle (30) assembly. The adjustment bars (20) of these adjustment bar (20)-support angle (30) assemblies are connected to each side of the main body (10) so that they can move freely in the axial direction. As shown in FIG. 3, when the adjustment bar (20) is inserted into the center of the main body (10), the adjustment bar (20)-support angle (30) assemblies on both sides are brought closer together, reducing the frontal width of the entire installation device. When the adjustment bar (20) is pulled out to the outside of the main body (10), the adjustment bar (20)-support angle (30) assemblies on both sides are separated from each other, expanding the frontal width of the entire installation device.

[0027] The mutual proximity or separation operation of the adjustment bar (20)-support angle (30) joints on both sides of the main body (10) allows the remaining adjustment bar (20)-support angle (30) joints to be inserted or withdrawn at the same distance when only one side adjustment bar (20)-support angle (30) joint is inserted or withdrawn, thereby preventing the external center point of the main body (10) from being biased in the entire installation device and making it easy to set the balance of the entire device configuration.

[0028] The simultaneous movement of the two-sided adjustment bar (20)-support angle (30) assembly in this invention is achieved by a configuration in which a pinion (15) is mounted so as to be freely rotatable at the center of the main body (10) as shown in FIG. 4, and a rack (25) is formed on the inner surface of the other end of the support angle (30) of the adjustment bar (20), so that the rack (25) and the pinion (15) mesh with each other.

[0029] That is, as shown in FIG. 4, in the adjustment bar (20)-support angle (30) assembly that is coupled to each side of the main body (10), the adjustment bars (20) of each of the two adjustment bar (20)-support angle (30) assemblies are not only parallel to each other in a plane but also overlap each other in a frontal view, and among the pair of adjustment bars (20) constituting each adjustment bar (20)-support angle (30) assemblies, a rack (25) is formed on the inner surface of the adjustment bar (20) on the side of the main body (10) center, and a pinion (15) that rotates freely around a rotation axis fixed to the center of the main body (10) is mounted on the center of the main body (10), so that the rack (25) of the two adjustment bar (20)-support angle (30) assemblies is simultaneously engaged with both sides of the pinion (15).

[0030] Accordingly, when one side of the adjustment bar (20)-support angle (30) assembly is moved in the axial direction of the adjustment bar (20), the pinion (15) engaged with the rack (25) rotates, and the other side of the adjustment bar (20)-support angle (30) assembly also moves simultaneously. As a result, even if the overall width of the device increases or decreases due to the movement of the adjustment bar (20)-support angle (30) assembly, the center position of the main body (10) can always be accurately maintained.

[0031] In order to stably induce axial movement of the adjustment bar (20) within the main body (10), as shown in FIG. 4, a guide path (12) may be formed inside the main body (10), and as described above, since the adjustment bar (20) is closely overlapped inside the main body (10), it is preferable that the planar width of the guide path (12) be set to twice the width of the individual adjustment bar (20).

[0032] Meanwhile, as shown in FIG. 1, the present invention is utilized in a manner connected to a skid bar (91), which is a landing component at the bottom of a drone (90). A reciprocating plate (40) and a capture part (45) are configured as means to connect the skid bar (91) and the main body (10). These reciprocating plates (40) and capture parts (45) also perform movement accompanied by the mutual proximity or separation movement of the aforementioned two-sided adjustment bar (20)-support angle (30) assembly.

[0033] That is, as shown in FIG. 4, a plurality of guide grooves (13) are cut and formed in the upper plate of the main body (10), and a protrusion (23) is formed on the upper surface of the adjustment bar (20), and a reciprocating plate (40) is attached to the upper end of the protrusion (23) that passes through the guide groove (13) upward. Thus, when one adjustment bar (20) is pressed into the main body (10) or pulled out to the outside of the main body (10), the pinion (15) engaged with the rack (25) rotates, and in the process of the other adjustment bar (20) also being pressed into the main body (10) or pulled out to the outside of the main body (10), the two reciprocating plates (40) connected to each adjustment bar (20) also move the same distance.

[0034] Accordingly, the capture part (45) that mutually connects the lower part of the skid bar (91) of the drone (90) and the reciprocating plate (40) also moves together with the reciprocating plate (40), so that the skid bar (91) can be accurately and stably fixed to the upper center of the main body (10) without a separate center setting operation.

[0035] In particular, even if the shape and width of the lower part of the skid bar (91) change by replacing the drone (90) or replacing the skid bar (91) of the drone (90), the mounting device of the present invention, including the main body (10), can be accurately and stably installed at the lower center of the drone (90) by only moving the adjustment bar (20)-support angle (30) assembly and the reciprocating plate (40), without any modification to the mounting device of the present invention.

[0036] In the present invention, a screw-compressed fixed-type capture unit (45) as shown in FIG. 2 and FIG. 4 is applied as a means of fixing the skid bar (91) of the drone (90) to the reciprocating plate (40), but various other compression or fixing means may also be applied.

[0037] Thus, through the present invention, when installing an attachment (35) on a drone (90), it is possible to stably distribute the weight of the attachment (35) while stably setting or maintaining a highly precise balance state, and in particular, even if the specifications of the drone (90), including the skid bar (91), change, it is possible to respond flexibly without replacing or modifying the attachment installation device.

[0038] Meanwhile, FIGS. 5 and 6 are configured to enable fine weight distribution in order to further improve the precision of the balance setting of the symmetrical mounting device of the present invention. A plurality of coupling grooves (62) are formed on the bottom surface of the main body (10) and arranged radially with the center point of the main body (10) as the axis. A steel plate (63) is attached inside the coupling groove (62), and a magnetic weight (60) is magnetically attached to the steel plate (63).

[0039] The iron plate (63) attached inside the coupling groove (62) is, as in the dictionary sense, an iron plate to which a magnet can be attached by magnetic force, and the magnetic weight (60) is a weight made of magnet, and the magnetic weight (60) attached by magnetic force to the iron plate (63) inside the coupling groove (62) can freely adjust its attachment position and quantity, thereby allowing the center of gravity of the device of the present invention to be finely adjusted.

[0040] These self-attaching weights (60) and coupling grooves (62) are arranged radially with the center point of the bottom surface of the main body (10) as an axis, as shown in FIGS. 5 and 6, and in the illustrated embodiment, they are arranged in a cross shape with respect to the center point of the bottom surface of the main body (10) to adjust the left-right balance and front-back balance of the mounting device of the present invention.

[0041] In addition, as shown in FIG. 5, a spherical protrusion (70) with a spherical surface formed on the lower side is formed at the center of the bottom surface of the main body (10). This spherical protrusion (70) is configured to allow for determining the balance state of the mounting symmetrical installation device of the present invention. As shown in the lower part of FIG. 5, the mounting symmetrical installation device of the present invention can be utilized by mounting it so that the spherical protrusion (70) is seated on the upper part of a flat support and then checking whether it is maintained horizontally.

[0042] In addition, a standard nut (17) and standard bolt (77) system for connecting the device to a support means such as a tripod or gimbal is applied to a standard commercial surveying device or photographic device. As shown in FIG. 6, the standard nut (17) is formed at the center of the bottom surface of the main body (10), and the standard bolt (77) is formed on the other side of the spherical protrusion (70), so that the spherical protrusion (70) can be attached or detached as needed.

[0043] In particular, by applying the standard nut (17) and standard bolt (77) system to the attachment and detachment of the spherical protrusion (70), the symmetrical mounting device of the present invention can be mounted not only on a drone (90) but also on a support such as a tripod as shown in the lower part of FIG. 6, and can also be mounted on a gimbal, although not illustrated in the drawing.

[0044] By mounting the tripod or gimbal of the symmetrical mounting device of the present invention, it becomes possible to utilize the mounting device of the present invention not only for shooting or surveying work using a drone (90) but also for work performed by human personnel and various other mobile bodies or support bodies.

[0045] In addition, through the aforementioned fine balance adjustment configuration using the self-adjusting weight (60) and the detachable configuration of the spherical protrusion (70), the entire mounting device can be made lighter by easily removing the self-adjusting weight (60) and the spherical protrusion (70) when fine balance adjustment is not required.
